In this paper, we investigate the transport of resolved turbulent stresses in a plane channel flow subjected to spanwise rotation using the method of large-eddy simulation (LES). We present both the general and simplified transport equations for the resolved turbulent stresses, which are essential for understanding the unique pattern of turbulent kinetic energy production in a rotating system. Numerical simulations are performed using a dynamic nonlinear model (DNM) for closure of the filtered momentum equation. The turbulent flow field studied in this research is characterized by a Reynolds number Reτ = 150 and various rotation numbers Roτ ranging from 0 to 7.5. In order to validate the LES approach, turbulent statistics obtained from the simulations are thoroughly compared with the available experimental and direct numerical simulation results.
